Welcome to the Albert Ellis Institute (AEI), a world-renowned psychotherapy institute committed to advancing emotional well-being through the study and application of effective, short-term therapy with long-term results.

AEI coordinates research and provides continuing education for mental health professionals, self-help workshops for the public and affordable psychotherapy for adults, couples, children, families and groups.

AEI's therapeutic approach is based on rational emotive behavior therapy (REBT), the pioneering form of cognitive behavior therapy. REBT is an action-oriented psychotherapy that teaches individuals to examine their own thoughts, beliefs and actions and replace those that are self-defeating with more life-enhancing alternatives.

REBT was developed in 1955 by Albert Ellis, Ph.D., who founded AEI in 1959. Dr. Ellis is widely recognized as one of the most influential psychologists of all time. Dr. Ellis served as President Emeritus of AEI, which is located in New York City.

AEI is a 501(c)(3) non-profit organization chartered by the Regents of the University of the State of New York.
